Hematological changes following infection of animals with the virus of epidemic influenza

Summary

Data on hematological changes in 23 ferrets, 53 white mice, and eight piglets are presented. The changes took place and after infection by the virus of influenza Type A. Both the number of leucocytes and the leucocytic formulas were studied. Hematological data were compared with the data of pathologicoanatomical bacteriologicaland virological investigation of these animals.

Observations showed that there was a tendency towards decrease of the number of leucocytes (in mice and pigs) or to considerable leucopenia (in ferrets) in virus nonmicrobic pneumonia. In presence of microbes regular pronounced and prolonged neutrophilic leucocytosis was noted.
